A film is formed at the droplet surface, so that no air is included in the lens, i.e., a filling rate of is achieved. Parylene is more flexible than metals; therefore, by integrating electrodes beneath the liquid lens coated with parylene, the lens can be deformed to vary the focal length according to the voltage applied to the electrodes .

Some of the terminology that describes the different types of reflective sheeting can be confusing. This article is going to define the terms enclosed lens and encapsulated lens reflective sheeting. These terms have to do with the construction of the reflective film. These 2 methods of construction also define the look and feel of the tape.
